Thats kind of touchy. You can not have a firearm readily accessable to a felon, no matter what the felony is for. I would say that since it is his legal residence, I would not do it. That is one of those better safe than sorry kinda things. I don't know of anything that says one way or another, but I would say that you should just skip it while you are there just to save yourself the hassle.
Again, i don't know for sure how the cops would view it, but there is my opinion anyway.
